Aio's that don't leak is a tall order. They are the least customizable option in for cloth diapers.

I like blueberry simplex best because they can be added to easily. We did use grovia ones overnight for several months but I ended up not liking them because of the microfiber and the awkward fit that the one row of waist snaps cause.

BG elementals are the trimmest but whether they leak or not depends on if you have a light wetter. No AIO hold a lot so they could all leak if you have a heavy wetter. Microfiber would be the worst because it leaks before getting full since it compress

If you are into Etsy I would seriously recommend this heavy wetter diaper from PNPBabyClothDiapers, this is my favorite Etsy shop to buy diapers from. You will need a cover, wool in my opinion is the best because with this combo it’s completely bulletproof.

AIOs that do not leak are not a thing imo. Grovia ones are a good suggestion but for me I had trouble getting the microfiber on the shell to not stink. I also find them to fit weird and be a tiny bit bulky. The one row of waist snaps is not my friend. I like blueberry simplex the best because it has a pocket for extra absorbency.

I don't find aios to be that much easier than other options. I do like them and use them but not as my main diaper. I guess I'm trying to say he cautious about committing to a whole stash of them

We took a cloth seminar, and decided on Funky Fluff. They work as Pocket, prefold, and all in one. It’s your choice and comes in two options. Moisture wicking jersey, and bamboo. And also have a trim fit. We tested out and played with as many options as possible.

The Grovia One didn’t fit my skinny kiddo. I tried at 3 stages and the legs gapped unless I removed a piece of the insert. I love the original bum genius elemental. Whenever they show up on Cottonbabies.com I buy one. I also love Smartbottoms AIO. The key to both of these particular AIO is figuring out how to fold the padding. For naps though I always use Bumgenius 5.0. I stuff with bamboo flats, bamboo inserts, thirsties hemp prefolds or inserts in various combos. I have thirsties cotton doublers that I use with the hemp prefolds and occasionally add to the aio if I’m going to be out and about with the kiddo.

have you tried the funky Fluff bamboo inserts? From everyone I have spoken to they are pure heaven and rarely need extra stuffing. (Their hemp boosters are supposed to be great too but absorb much more slowly)

I haven’t. I use Kawaii Baby organic 5 layer bamboo inserts, thirsties hemp inserts and prefolds and Oso Cozy bamboo flats pad folded. I put in either 2 kawaii bamboo (super trim), a thirsties hemp under a kawaii bamboo, thirsties hemp prefold under a thirsties cotton booster and a flat by itself. All of these work great. All of my pockets are BumGenius. No leaks and she’s 2 now. Night time I use a hemp fitted with a Flip or Smart Bottoms cover.
